Which Model Years This Covers
This guide covers water intrusion on every Winnebago EKKO model year from 2022 to 2026. Chassis generation drives most of the diagnosis, so the causes below are organized by year range — find your year and start there. Not sure of your chassis year? On Sprinter-based RVs the chassis model year is often one year behind the RV title year; verify with the 10th character of the VIN or the door-jamb sticker.
Causes and Diagnosis by Year Range
2022–2026
The 2022–2026 Winnebago EKKO sits on the Ford Transit AWD chassis with the 3.5L EcoBoost gasoline V6. No DEF, no DPF, no glow plugs — emissions maintenance is dramatically simpler than Sprinter. Early Transit-based EKKOs (2022–2023) had first-year fit-and-finish issues; by later 2022–2026 builds Winnebago had stabilized production. Water heater plumbing on the Transit is routed closer to the floor than on Sprinter-based RVs, so sub-freezing protection requires running the furnace rather than relying solely on the diesel heater.
For the 2022–2026 model year, the most common root causes involve age-related wear, the specific engineering tolerances of the 2022–2026 production run, and documented chassis issues noted in the chassis context above.

Model Year Notes
Production changes, recalls, and running fixes that matter for this vehicle, by year:
2022
2022 is the first Transit model year used in Winnebago EKKO production. Early-build fit-and-finish issues were documented extensively in owner forums — specifically around upfitter harness routing, water-pump plumbing, and water-heater venting. Most were addressed via mid-year Winnebago production updates and dealer-applied fixes. A 2022 EKKO's production date matters: early-2022 builds carry more of these issues than late-2022 builds.
2023
2023 Transit-based EKKOs benefit from Winnebago's first full production year of refinements over the 2022 launch. HVAC unit recall timing affects multiple 2023 production dates — verify status by VIN before assuming a fault is not recall-covered. By late 2023, most launch-era upfitter quirks had been production-addressed, making late-2023 builds noticeably different from early-2022s.
2024
The 2024 Ford Transit EcoBoost received minor calibration updates that improved towing performance modestly over earlier years. On the EKKO body specifically, 2024 introduced subtle floorplan and upfitter-package refinements. The 10-speed automatic carries forward unchanged in terms of service procedures; any transmission diagnosis on a 2024 Transit-based RV uses the same playbook as 2022-2023.
2025–2026
The 2025–2026 Ford Transit retains the 3.5L EcoBoost V6 and the 10-speed automatic that debuted in earlier Transit years. By this model year the EKKO platform had reached full production maturity; most 2025–2026 complaints trace to RV-side systems rather than Transit chassis issues. Full factory warranty applies to most 2025–2026 units.
